hmmmmm can see this kicking off!
i work from home half the week and i'm in the office the other half.
i guess it all depends on what you do during the day which affects how 'knackered' and 'frazzled' you are.
quality time with dd wears me out! but so does my time in the office when we're all rushing around like headless chickens.
its too subjective to say which is more tiring.
everyone has different lifestyles and to a certain extent everyone has different stamina levels, etc.
having children is tiring!
